This dissertation transforms a set of system complexity reduction problems to feature selection problems. Three systems are considered: classification based on association rules, network structure learning, and time series classification. Furthermore, two variable importance measures are proposed to reduce the feature selection bias in tree…

The articles in this volume indicate that typological research on college students has been around for about half a century and has a strong presence in the literature on college students. The underlying assumption in typological research is that outcomes of interests (for example, student attitudes, experiences, and outcomes) and students…

Educators may start off a school year with the best of intentions for staying organized, but by about November, they quickly find their systems, energy and motivation starts to dwindle. By March, they can't even see their desk, and have hundreds of e-mails in their inboxes. Incorporating a few organizational strategies at the beginning of the…

Youth subcultures in Russia have become more like those found in other societies. The article presents typologies of youth subculture types and trends. Attitudes toward them vary by urban/rural, economic, educational, and geographic characteristics. (Contains 2 tables and 2 figures.)

Group care programs, while ubiquitous, are not clearly differentiated despite differences in the population served, size, auspices, and program activities, to name a few. Words like group care, residential care and residential treatment are often used interchangeably in policy, research and practice. This paper introduces reporting standards that…

This research examines the nature of comprehended meanings that do not match those of the author. These meanings were generated by two groups of fourth graders after reading a narrative or expository text. Readers read their respective texts aloud, followed by a recall and probes. Reading behaviours were examined to establish that processing…

Three experiments used postclass formation within-class preference test performances to evaluate the effects of nodal distance on the relatedness of stimuli in equivalence classes. In Experiment 1, two 2-node four-member equivalence classes were established using the simultaneous protocol in which all of the baseline relations were trained…

The paper addresses the paradox of value-free science and the need for value-oriented management education. Taking the values discussion in the German management community as an example, we identify two stereotypes in management literature: an allegedly value-free scientist who limits responsibility to economic aims and a value-laden academic who…

Very little research has examined the dynamics within couple relationships that may lead to situational couple violence (SCV; M. P. Johnson, 2006a; K. H. Rosen, S. M. Stith, A. L. Few, K. L. Daly, & D. R. Tritt, 2005). To enhance understanding of these dynamics, we conducted a qualitative analysis of interviews with 11 couples previously…

This article extends recent findings that presenting semantically related vocabulary simultaneously inhibits learning. It does so by adding story contexts. Participants learned 32 new labels for known concepts from four different semantic categories in stories that were either semantically related (one category per story) or semantically unrelated…

When participants must classify their recognition experiences as remembering or knowing, variables often have dissociative effects on the two judgments. In contrast, when participants independently rate recollection "and" familiarity only parallel effects have been reported. To investigate this discrepancy we compared the effects of masked priming…

Retrieving information from memory produces more learning than does being presented with the same information, and the benefits of such retrieval appear to grow as the delay before a final recall test grows longer. Recall tests, however, measure the number of items that are above a recall threshold, not memory strength per se. According to the…

Participants made categorical or coordinate spatial judgments on the global or local elements of shapes. Stimuli were composed of a horizontal line and two dots. In the Categorical task, participants judged whether the line was above or below the dots. In the Coordinate task, they judged whether the line would fit between the dots. Stimuli were…

The statistical classification of "N" individuals into "G" mutually exclusive groups when the actual group membership is unknown is common in the social and behavioral sciences. The results of such classification methods often have important consequences. Among the most common methods of statistical classification are linear discriminant analysis,…

Cognitive psychologists have begun to address how motivational factors influence adults' performance on cognitive tasks. However, little research has examined how different motivational factors interact with one another to affect behavior across the life span. In the current study, the authors examined how children perform on a classification task…
